Description

Technical Field

[0001] The present invention relates to the field of communication networks, and particularly to a dual-link dynamic selection and routing optimization method based on the integration of ad-hoc network and 5G. Background Art

[0002] With the rapid development of wireless communication technologies, especially in the gradual popularization and application of ad-hoc networks and 5G networks, the traditional communication network architecture has gradually revealed some deficiencies, especially in terms of bandwidth utilization, link reliability, network stability, and flexibility. In scenarios such as emergency communication, military communication, Internet of Things, and smart cities, it is often necessary to cope with complex communication environments and extremely high reliability requirements. To solve these problems, the industry has proposed various solutions for the integration of ad-hoc networks and 5G networks to achieve an efficient, stable, and highly robust communication network.

[0003] An ad-hoc network is a technology that can automatically form a network based on the interconnection between nodes without the support of fixed infrastructure. It has high flexibility and self-adaptability and can provide effective communication guarantees for users in emergencies or disasters. However, traditional ad-hoc networks have the following problems:

[0004] 1. Link selection problem. Due to the unstable signal propagation between network nodes, the quality of the link is affected by environmental interference and equipment failures. Traditional ad-hoc networks often rely on a single link path and lack a dynamic link selection and optimization mechanism, resulting in unstable network performance.

[0005] 2. Insufficient bandwidth allocation. In an ad-hoc network, the bandwidth of nodes is limited by the link quality and network topology, resulting in the inability to meet the requirements of real-time communication and large-volume data transmission when the number of users increases or the data traffic grows.

[0006] 3. Insufficient routing optimization. The existing routing algorithms for ad-hoc networks are usually relatively simple and do not fully consider factors such as link quality and node load, easily resulting in problems such as long routing paths, high delays, and low throughput, affecting the user experience.

[0007] To overcome the above problems, the introduction of 5G networks provides a new solution for ad-hoc networks. 5G networks have higher bandwidth, lower latency, and stronger network stability, and can support large-scale and high-density user access. The deployment and coverage of 5G networks face many limitations, especially in remote areas or disaster sites, where the construction of 5G base stations is restricted by geographical and economic conditions. Combining ad-hoc networks with 5G networks and leveraging their advantages has become an ideal solution.

[0008] The current self-organizing network and 5G network integration solutions, although achieving certain progress in some scenarios, still have some deficiencies:

[0009] 1. The link selection and handover mechanism is single. Existing solutions usually rely only on signal strength or preset rules for link handover, lacking a dynamic and intelligent link evaluation and selection mechanism.

[0010] 2. Bandwidth and traffic management are not flexible. Existing bandwidth allocation and traffic scheduling strategies are relatively simple and cannot perform precise control according to different service requirements (such as real-time voice, video transmission, large-flow data transmission, etc.), resulting in low utilization efficiency of network resources.

[0011] 3. The routing strategy lacks intelligence. Existing routing algorithms often do not fully consider link quality and network load, resulting in unstable routing paths and being easily affected by link failures or environmental changes.

[0012] How to achieve intelligent selection of dual links, dynamic routing optimization, and bandwidth management in the integration environment of self-organizing networks and 5G networks to ensure communication quality and user experience has become a technical problem to be solved urgently. Summary of the Invention

[0049] The present invention has the following beneficial effects: By integrating the ad-hoc network and the 5G network and combining technical means such as dual-link selection, bandwidth management, and intelligent routing optimization, the present invention realizes an efficient, stable and flexible communication network. This method can adapt to various communication environments, solves problems such as link selection, bandwidth allocation, and routing optimization in the integration of the ad-hoc network and the 5G network in the prior art, and has important technical value and broad application prospects.

[0050] 1. System Architecture and Network Topology

[0051] The core idea of the present invention is based on the integration of the ad-hoc network and the 5G network, and adopts a dual-link mechanism to realize the intelligent selection and dynamic switching of communication links. Specifically, each ad-hoc network node has two communication links: one is a link based on the ad-hoc network, and the other is a link based on the 5G network.

[0052] Figure 1 The system architecture of the present invention is shown, where each node is equipped with two links. The ad-hoc network link is mainly used to cover a wide area and can communicate in an environment without infrastructure support; while the 5G link provides high-speed and low-latency communication services through 5G base stations. The two links dynamically select the link with the best quality for communication through the link optimization mechanism.

[0053] 2. Link Selection Mechanism

[0054] Each ad-hoc network node collects data such as signal strength, latency, bandwidth, and packet loss rate of two links in real time through a link quality monitoring module and evaluates them. Based on these monitoring results, the present invention proposes a link optimization mechanism to dynamically select the optimal link through the following steps:

[0055] (1) Link quality assessment. The ad-hoc network node regularly collects the quality data of each link and generates a link quality report.

[0056] (2) Link optimization. According to the link quality report, calculate the comprehensive quality index (CQI) of each link. This index takes into account factors such as signal strength, latency, bandwidth, and packet loss rate and reflects the overall quality of the link.

[0057] (3) Link switching. When the quality of the currently used link drops below a preset threshold, the system will automatically switch to a link with better signal quality. The switching operation does not affect user communication and ensures communication stability.

[0058] Figure 2 Shows the specific process of link selection. As can be seen from the figure, each node automatically selects the best link for communication according to the change of link quality.

[0059] 3. Bandwidth management and priority scheduling

[0060] The present invention adopts a bandwidth priority scheduling strategy to maximize the utilization efficiency of network resources while ensuring the user experience. The specific strategy is as follows:

[0061] (1) Service type identification. According to different service requirements (such as real-time voice, video stream, large traffic data transmission, etc.), different priorities are assigned to each type of service. Real-time communication services (such as voice and video calls) have higher priorities, and non-real-time services (such as file transfer) are dynamically adjusted according to the network load.

[0062] (2) Bandwidth allocation. During the link selection process of each node, the system dynamically allocates bandwidth according to the service type and link quality. For real-time communication services, the system preferentially allocates links with lower latency and smaller bandwidth; for large traffic data transmission services, it preferentially selects links with larger bandwidth but higher latency tolerance.

[0063] (3) Traffic control. When the bandwidth of a certain link is insufficient, the system will adjust the traffic control strategy, such as reducing the bandwidth occupancy of non-real-time services, to ensure the communication quality of high-priority services.

[0064] Figure 3 Shows the process of bandwidth management and priority scheduling. As can be seen from the figure, how to allocate bandwidth according to service priority and link quality.

[0065] 4. Routing Optimization and Dynamic Routing Selection

[0066] In the case of the integration of ad hoc networks and 5G networks, how to select an appropriate routing path to ensure communication quality is an important aspect of the present invention. To achieve efficient routing optimization, the present invention proposes a dynamic routing selection algorithm based on link quality and network load.

[0067] (1) Dynamic routing algorithm. Each ad hoc network node calculates the optimal routing path according to factors such as network topology, link quality, and load conditions. The system will update the routing table in real time and automatically adjust the routing path according to changes in link quality.

[0068] (2) Load balancing. To avoid overloading of certain links or nodes, the system will distribute traffic to multiple links through a load balancing algorithm to ensure the stability and efficiency of the network.

[0069] (3) Link fault tolerance. When a link fails or its quality deteriorates, the system will dynamically adjust the routing and automatically switch to another link to ensure uninterrupted communication.

[0070] Figure 4 Shows the specific process of routing optimization. It can be seen in the figure how link quality and network load affect the selection of routing paths and demonstrates the dynamic adjustment process.

[0071] 5. Network Topology Structure

[0072] The ad hoc network nodes in the present invention adopt a hierarchical topology structure, which is specifically divided into a core layer, an access layer, and an edge layer. The core layer is responsible for the management and scheduling of the entire network. The access layer connects the core layer and the edge layer, and the edge layer is responsible for direct communication with user terminals.

[0073] The number of nodes in each subnet is less than 32, which can reduce the complexity of the network topology and improve the stability and reliability of the network. Physical links are used to connect different layers without consuming time slot resources, thus avoiding the problem of time slot resource conflicts in traditional ad hoc networks.

[0074] Figure 5 Shows the hierarchical topology structure of the ad hoc network. It can be clearly seen in the figure the physical connection methods of the core layer, the access layer, and the edge layer.

[0075] 6. Dual-Link Backup Mechanism for Ad Hoc Networks and 5G Networks

[0076] The ad hoc network nodes of the present invention support a dual-link backup mechanism for ad hoc network links and 5G network links. Through the link selection mechanism, the system can automatically switch between the two links to ensure the continuity of communication.

[0077] When a link fails or the signal quality deteriorates, the system will automatically switch to another link without affecting the user's communication experience.

[0078] Under normal circumstances, the system will select the optimal link for communication based on link quality and service requirements. This dual-link backup mechanism greatly improves the reliability and robustness of the system.

[0079] Although the embodiments of the present invention have been disclosed as above, it is not limited to the applications listed in the specification and embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the field, additional modifications can be easily made. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to the specific details and the illustrated examples here.
